Congratulations to Loket, who saw with astounding clarity what I did there for 5 of the last 6 weeks. I will let him explain:

What you've done these past weeks:

No turning back, and no going back.
( ͡° ͜ʖ ͡°) ( ͡° ͜ʖ ͡°) ( ͡° ͜ʖ ͡°) ( ͡° ͜ʖ ͡°) ( ͡° ͜ʖ ͡°)
You sure you want me to spoil what you've done?
OK then, don't hold me responsible for ruining it.

Final warning, no turning back once you cross this line.
This is the line I mentioned, you're now crossing it.
You've hidden the URL in the first words of the ITH description, using the same formatting as for the nonos.
This week: "Good game ya'll. Good luck!" = GGYgl
So, what do I win for noticing?

Previous weeks one by one, most recent first:
"Okay, I dumped ten "economical" games this time. They deserve a good home too!" = O94tE (I=9, d=4)
"Verify nono knowledge. Check down below." = vNk3d (C=3)
"Possible hint: leave position Z3 empty." = P8lPz (h=8)
"No one saw what I did there last week. I am disappoint =(" = 7BJ65 (Nothing? Not that I can think of at the moment.)
"Today's nono puzzles sound fun." = TnPSf

Loket is right. The code to enter my trains has been in the description of the ITH for 5 of the last 6 weeks. I know all of you probably got in anyway, but it's the mystery itself that's the fun part. As a reward, he chose 5 games from a list of 28 to receive as gifts. Good show!

On to the fun stuff!
